Beddar place?

For when you're WFH, but need those 🐠 office vibes?

My pet theory is that Steven Conrad wrote the role with his brother Chris in mind (who was excellent in Patriot! and would have been great starring in DTF! and has a small cameo as a cop!) but had to bring on a name like Bateman to get the show made.

I just published a deep-dive into the 250-hour build behind syntaqlite, a SQLite formatter and LSP I built using AI agents.

AI agents were the only reason built this after 8 years of wanting but there's a psychological toll to AI-assisted engineering.

Nice! I love the Web Share Target integration. Such an elegant way of interacting with a PWA.

Quantization from the ground up | ngrok blog A complete guide to what quantization is, how it works, and how it's used to compress large language models

I spent 2 months learning about quantization and am extremely proud of the post I've written about it. I think these are some of the nicest visuals I've ever made, and I love how this compression technique invented in 1898 is being used on the bleeding edge in 2026.

This must've been one of the most challenging things I've worked on in a while. Thanks Bloomberg for sponsoring my work on this, and everyone who helped shipping a fix in time!

Thank you! I don't think it was obvious to anyone that you had to click on the Waterfall column header to get back the original sort order.

ECMAScript excitement 😉

This week in NY @tc39.es advanced these proposals 🎉

4⃣ Intl Era/Month Code
4⃣ Temporal
3⃣ Import Text
2⃣.7⃣ Error Stack Accessor
2⃣.7⃣ Iterator Includes
2⃣ Intl Unit Protocol
2⃣ Thenable Curtailment
1⃣ Error Code Property
🗑️ Dynamic Import Host Adjustment

Code example showing the usage of Temporal.ZoneddateTime ```js // London DST starts: 2026-03-29 01:00 -> 02:00 const zdt = Temporal.ZonedDateTime.from( "2026-03-29T00:30:00+00:00[Europe/London]", ); console.log(zdt.toString()); // → "2026-03-29T00:30:00+00:00[Europe/London]" const plus1h = zdt.add({ hours: 1 }); console.log(plus1h.toString()); // "2026-03-29T02:30:00+01:00[Europe/London]" (01:30 doesn't exist) ```

Temporal is now Stage 4 at TC39 🎂🎂🎂

Thanks to all the other champions of JavaScript's new date-time API. It has been a wild ride over many years!

I wrote a blog post explaining how we got here 📜

bloomberg.github.io/js-blog/post...

A JSON file representing a source map. The code contains: { "version": 3, // Always the integer 3 "file": "out.js", // Optional: name of the generated file "sourceRoot": "", // Optional: prefix prepended to each entry in "sources" "sources": ["foo.js", "bar.js"], // Required: list of original source URLs/paths (or null) "sourcesContent": [null, null], // Optional: inlined source text, aligned with "sources" "names": ["src", "maps"], // Optional: symbol names referenced by "mappings" "mappings": "A,AAAB;;ABCDE", // Required: encoded mapping data (base64-VLQ deltas) "ignoreList": [0] // Optional: indexes into "sources" considered "third-party" }

Source maps are a vital part of modern web development, but the lack of a standard made it impossible for us to add new features or improve the debugging experience.

This is the story of how we standardized source maps and how we continue to ship features through standards 📜

Bloomberg JS Blog The official Bloomberg JavaScript blog - insights, tutorials, and best practices from Bloomberg's JavaScript engineering team.

Some time ago, @jonkuperman.com & @tchetwin.bsky.social had a dream for the JS engineers at Bloomberg to be more public about the cool JS work we have going on.

That dream has come true - now we have a blog platform 🎉

(You'll see more articles over the next few days)

Dark-themed code snippet showing URLPattern examples on MDN: two JavaScript blocks matching "/books" and "/books/:id" with console.log outputs.

🆕 The URL Pattern API is Newly Available!

Use it to match and extract parts of URLs, no need to reinvent routing logic. Supports literals, wildcards, named groups, and even regex constraints.

Temporal is the replacement for the Date API.

I refuse to shut up about this: NYC started charging $9 to bring a car into our most transit-rich zone, the haters & trolls predicted doom, but traffic evaporated instantly and here’s Times Square tonite (even after the holiday tourists have left). For a better future, build transit & price driving!
